The iPhone 13 Pro Max, a sophisticated flagship from Apple, continues to be a highly sought-after device, prized for its stunning ProMotion Super Retina XDR display, advanced A15 Bionic chip, and professional-grade camera system.
Its robust build and premium materials offer a compelling user experience, making it an integral part of daily life for countless individuals. While durable, the expansive display of the iPhone 13 Pro Max remains susceptible to accidental damage, often leading to a cracked screen. Opting for a screen replacement is a common solution, but it's crucial for owners to be aware of potential issues that can arise post-repair, especially if not handled by experienced professionals.

A Deep Dive into Common iPhone 13 Pro Max Problems After Screen Replacement
Getting your iPhone 13 Pro Max screen replaced is a common procedure, but it's not always a guaranteed flawless outcome, especially if the repair is not performed by a qualified technician using genuine or high-quality OEM-specification parts. Awareness of potential issues is key to ensuring a successful repair experience.
Here are some of the most common problems users might encounter after an iPhone 13 Pro Max screen replacement:
-
Face ID Malfunction:
- Cause: This is perhaps the most critical and frustrating issue. The TrueDepth camera system (which enables Face ID) is incredibly sensitive and inextricably linked to the original logic board. If the front camera/sensor assembly, which is often transferred from the old screen to the new one, is damaged, misaligned, or if the replacement screen is not genuine or OEM-spec, Face ID can permanently stop working. Apple has implemented strict measures that tie these components to the original device.
- How to Avoid: Only trust repairs to technicians who understand Apple's pairing requirements and have the expertise to meticulously transfer the Face ID components without damage.
-
"Important Display Message" Warning:
- Cause: After replacing the screen on an iPhone 13 Pro Max (and newer models), you might see a persistent message in Settings > General > About, stating: "Important Display Message - Unable to verify this iPhone has a genuine Apple display." This occurs even with genuine Apple parts if the repair is not done by Apple or an Apple Authorised Service Provider (AASP) who can calibrate the new display with Apple's proprietary tools. While the message doesn't affect functionality, it can be annoying and impact resale value.
- How to Avoid: This warning is generally unavoidable for independent repairs as only Apple/AASPs have the specific software tools to clear it. However, a reputable independent repairer will use high-quality parts that ensure the display itself functions perfectly despite the message.
-
Loss of True Tone Functionality:
- Cause: True Tone adjusts the display's white balance to match the ambient light, providing a more natural viewing experience. The ambient light sensor data (which is often transferred from the old screen) needs to be correctly programmed to the new display. If the original sensor is damaged during transfer, or if the new screen is a low-quality aftermarket part without the necessary integrated components, True Tone might cease to function.
- How to Avoid: Ensure the repairer meticulously transfers all necessary small components from your original screen and uses a high-quality replacement display.
-
Reduced Brightness or Inaccurate Colors:
- Cause: This usually points to a low-quality aftermarket screen. Cheaper replacement displays often lack the same brightness, colour accuracy, contrast ratios, and power efficiency as the original Apple Retina XDR display.
- How to Avoid: Always insist on genuine or high-quality OEM-specification parts. Ask the repair shop about their part sourcing and warranty.
-
Unresponsive or Glitchy Touchscreen:
- Cause: This can result from a faulty digitizer layer within the new screen assembly, improper connection of the display's flex cables to the logic board, or even a defect in a low-quality aftermarket part.
- How to Avoid: Choose a reputable repairer with experienced technicians who meticulously handle connections and use reliable parts.
-
Compromised Water Resistance:
- Cause: Apple iPhones use adhesive seals to provide water and dust resistance. During a screen replacement, these seals are broken. If the new adhesive is not properly applied, or if low-quality adhesive is used, the device's water resistance will be significantly compromised.
- How to Avoid: A professional repair shop will use high-quality, pre-cut adhesive seals and ensure proper application, although they typically cannot guarantee the original factory water resistance after a repair.
-
Battery Drain:
- Cause: A low-quality aftermarket screen might be less power-efficient than the original, leading to increased battery consumption. Alternatively, improper handling during the repair could inadvertently damage the battery or its connection.
- How to Avoid: Opt for quality parts and a trusted technician to minimise the risk of additional issues.
